I used KSDK and FlexCAN. (MK60DN512)

How work individual mask for mailBox.?

If I apply the fifo, personal masks work at mainlbox?

Individual mask can be set up as filters?

Hi,

The below FlexCAN driver API function using to set Receive message buffer ID mask type:

FLEXCAN_DRV_SetRxMaskType(flexcanInstance, kFlexCanRxMaskGlobal);

The FlexCAN MB mask has two types as below definition:

/*! @brief FlexCAN receive mask type.*/

typedef enum _flexcan_rx_mask_type {

kFlexCanRxMaskGlobal, /*!< Receive global mask*/

kFlexCanRxMaskIndividual /*!< Receive individual mask*/

} flexcan_rx_mask_type_t;

If customer want to use Receive individual mask, please use below code:

FLEXCAN_DRV_SetRxMaskType(flexcanInstance, kFlexCanRxMaskIndividual);

When using the FIFO, it will check FlexCAN control 2 register (CANx_CTRL2) register [MRP] bit ,

which is set the matching process starts from the Mailboxes and if no match occurs the matching

continues on the Rx FIFO.

Wish it helps.

Have a great day,
Ma Hui
